Since I gravitate towards figure drawing, anatomy is a very important part of the artwork I make. I'm blessed with a good eye for proportions, however, getting the figure and the skeleton to look right independent of each other is very different from getting them to match up together. It it a difficult way to approach anatomy but it it is ultimately worthwhile.
The hardest part of these drawings is that you have to take the skeleton that is available and adjust it to fit your own anatomy. You end up learning more about yourself without even realizing it.
Of the three, this one is my favorite. I think it is the best self portrait but I also love the composition of the background. I ended up positioning myself between two huge mirrors and was able to capture the ongoing reflection of the frames.
